Abstract
The invention relates to an autoclaved aerated concrete block and a preparation method and belongs to the technical field of production of building materials. The autoclaved aerated concrete block is prepared from river sand, coal ash, lime, cement, gypsum, aluminite powder and water. The preparation method comprises the following steps: adopting a ball grinding mill to wet mill the raw materials except aluminite powder, lime and cement into powder, mixing and stirring the powder, after the temperature of the mixture reaching 45 DEG C, adding the aluminite powder, uniformly loading the cement and the dry-milled lime into a stirrer, uniformly mixing, feeding the mixture in a die, after compression moulding, cutting a green body with a cutting machine, feeding the cut green body in a steam retort, and steaming for 10 hours to obtain the finished product. According to the invention, river sand and waste of a power plant are adopted as the main raw materials, and are light in weight, excellent in thermal insulation property and sound insulation property, high in anti-permeability, and excellent in fire resistance and corrosion resistance, so that the problem about the treatment of plenty of waste of the power plant is solved, and the pollution to a city caused by coal ash is reduced; the emission of three wastes (waste gas; waste water; industrial residue) during the production process is avoided, the technology is simple and easy to master, the occupied area of production is small, the energy consumption is low, and autoclaved aerated concrete block is easy for popularization.
Description
Technical field
The present invention relates to a kind of autoclave aerated concrete building block and preparation method, belong to material of construction production technical field.
Background technology
The building brick of current China is mainly clay brick, but the power consumption of the sintering procedure of clay brick is high, breaking-up field, on September 26th, 2012, the National Development and Reform Commission announces, China will progressively limit use clay-ware or forbidding solid clay brick in " 12 " period in hundreds of the cities such as Shanghai and relevant county town.
Along with the development of power industry, the flyash quantity discharged of coal-burning power plant increases year by year.A large amount of flyash does not add process, will produce airborne dust, atmosphere pollution; River can be caused to silt up if enter water system, and toxic chemical substance wherein also can work the mischief to human body and biology.Can turn waste into wealth with the technology that this plant residue of flyash prepares autoclave aerated concrete building block for main raw material, again for building industry provides starting material while contaminated solution.But the making formula of the autoclave aerated concrete building block reported at present is unreasonable, causes block strength poor, production technique and making equipment complexity, place floor space is large, and the production cycle is long.
Summary of the invention
The object of the invention is to, for above-mentioned the deficiencies in the prior art, there is provided a kind of formula rationally, block strength is high, and make full use of power plant's waste material, solve the pollution of fly ash in electric power plant, to solve existing autoclave aerated concrete building block intensity difference, the autoclave aerated concrete building block of production technique and making equipment challenge and preparation method.
The present invention realizes above-mentioned purpose by the following technical solutions:
A kind of autoclave aerated concrete building block, it is characterized in that, it is made up of the raw material of following weight per-cent:
River sand 50%, flyash 20%, lime 15%,
Cement 10%, gypsum 3.95%, aluminium powder 0.05%,
Water 1%.
A preparation method for autoclave aerated concrete building block, is characterized in that, it comprises the steps:
First with ball mill by mixing after other raw material wet-millings to powder except aluminium powder, lime, cement and stirring, after thing temperature to be mixed reaches 45 DEG C, add aluminium powder, after 0.5 ~ 1 minute by cement and dry grinding after lime evenly flow in stirrer; The raw material mixed is sent in mould, makes type at the pressure of 180 ~ 200 kg/cm; Again shaping aerated blocks base substrate is carried out precuring 2 ~ 5 hours under the envrionment temperature of 48 ~ 68 DEG C, then framed and aerated blocks base substrate are together hung on cutting bed, slough framed, with cutting machine, base substrate is cut, again the base substrate after cutting to be entered in steam still under the pressure of 25 ~ 30MPa steam pressure 10 hours, obtain autoclave aerated concrete building block finished product.
The present invention compared with prior art its beneficial effect is: compared with conventional clay, and autoclave aerated concrete building block quality provided by the present invention is light, good heat insulating, sound-proofing are good, impermeability is strong and fire-resistant corrosion-resistant; Therefore this building block can arbitrarily be cut has excellent processing characteristics; Have employed power plant's waste material is main raw material, and it contains a large amount of silicon-dioxide and aluminium sesquioxide and iron, calcium, has good stability, low density advantage; Solve the process problem of a large amount of power plant rubbish, decrease the pollution that flyash brings to city; Without " three wastes " discharge in production process, save time province ground, and productivity improves, production cost reduces; Quality product meets national standard, and intensity is high, cost is low, pollution-free; Whole production process raw material is easy to get, technique is simple and easy to grasp, floor space is little, energy consumption is low, is easy to popularize.
Embodiment
Below by specific embodiment, autoclave aerated concrete building block of the present invention is further described as follows (for every mould 2016 kilograms):
Each raw material is taken by above-mentioned raw materials formula and proportioning:
River sand 1008.0 kilograms, 403.2 kilograms, flyash,
302.4 kilograms, lime, cement 201.6 kilograms,
79.6 kilograms, gypsum, aluminium powder 1.0 kilograms,
20.2 kilograms, water.
The preparation method of this autoclave aerated concrete building block is as follows:
First with ball mill by mixing after other raw material wet-millings to powder except aluminium powder, lime, cement and stirring, after thing temperature to be mixed reaches 45 DEG C, add aluminium powder, after 0.5 ~ 1 minute by cement and dry grinding after lime evenly flow in stirrer; The raw material mixed is sent in mould, makes type at the pressure of 180 ~ 200 kg/cm; Again shaping aerated blocks base substrate is carried out precuring 2 ~ 5 hours under the envrionment temperature of 48 ~ 68 DEG C, then framed and aerated blocks base substrate are together hung on cutting bed, slough framed, with cutting machine, base substrate is cut, again the base substrate after cutting to be entered in steam still under the pressure of 25 ~ 30MPa steam pressure 10 hours, obtain autoclave aerated concrete building block finished product.
